It is well known that the sequential (premature) exercise of American-type warrants may be advantageous for large warrantholders, even in the absence of regular dividends, because using exercise proceeds to repurchase stock or to expand the firm’s scale increases the riskiness of an equity share

This study correlates the presence of exercise-related ventricular premature complexes with both exercise-induced ST-segment depression and coronary arteriographic and ventriculographic findings in 60 patients evaluated for chest pain. Of 38 patients in whom ventricular premature complexes were

and parasympathetic activity. It is not known if the autonomic nervous system related to ventricular arrhythmias during exercise. The purpose was to evaluate the HRA and HRR in patients with and without premature ventricular complex (PVC) during exercise, and to examine the factors that might affect HRA and HRR

SUMMARY To define the prevalence, frequency and characteristics of premature ventricular complexes (PVCs) in adults free of recognizable heart disease, we performed 24-hour ambulatory electrocardiography on 101 subjects (51 men and 50 women, mean age 48.8 years) in whom physical examination, chest

. It reveals hazardous exertional arrhythmias which in-dicate exercise testing should be interrupted. For ex-ample, three or more consecutive ventricular premature beats may be the prelude to ventricular tachycardia or fibrillation with exertional cardiac arrest. It also reveals postexertional ST segment

Summary Hypertension (high blood pressure; BP) is a leading contributor to premature death and disability from cardiovascular disease. Lifestyle modification that includes regular physical activity is often recommended to patients with hypertension as one of the first line treatments for lowering
